Description
Technical field
The utility model relates to a kind of butterfly valves, more particularly to a kind of butterfly valve and the locking locating snap ring of butterfly valve seat screw.
Background technique
The floating type valve seat of butterfly valve and being connected and fixed for valve body mainly use conventional soket head cap screw, soket head cap screw pair at present
Valve seat carries out pre-tightening the uncertainty for causing screw loading end position relative to fixed ring position, the spiral shell that pretightning force can only be leaned on to generate
Frictional force between line is locking, or installs spring washer additional under screw loading end, or installs disc spring additional, this structure energy when vibrating smaller
Preferable anti-loosing effect is enough played, under some special operation conditions, the vibration of valve is larger, and screw will loosen, and generates to valve
It influences；To ensure screw to the pretightning force of valve seat, then screw must have the controllability of displacement, and spring washer or disc spring are answered
Install 2 or more additional, therefore structure design and installation limited space is inconvenient.
Utility model content
In order to overcome the shortcomings of background technique, the utility model provides the locking stop of a kind of butterfly valve and butterfly valve seat screw
Ring solves the problems, such as that existing butterfly valve seat screw is easy to loosen.
Technical solution adopted by the utility model: a kind of locking locating snap ring of butterfly valve seat screw, including tie in a ring
The locking locating snap ring of structure, the locking locating snap ring are equipped with several screw mounting holes being arranged circumferentially, the locking stop
Ring outer ring is equipped with the elastic portion of annular bending.
The locking locating snap ring inner ring is equipped with several locking plates that can bend fixation, and the locking plate is arranged circumferentially and screw
Mounting hole is corresponding.
The locking plate is in the strip towards the center of circle.
The screw mounting hole is equipped with 8 altogether.
A kind of butterfly valve, including valve body, valve seat, stop collar, several screws；The stop collar is fixed in valve body, the valve
Seat is arranged between valve body and stop collar, and the screw is arranged circumferentially along stop collar, and passes through stop collar and offset with valve seat；
It further include locking locating snap ring, the locking locating snap ring is equipped with screw mounting hole corresponding with screw, described anti-
Loose locating snap ring outer ring is equipped with the elastic portion of annular bending；The screw passes through screw mounting hole and locking locating snap ring is fixed on limit
Ring, and the elastic portion is fitted closely with stop collar.
The locking locating snap ring inner ring is equipped with several locking plates that can bend fixation, and the locking plate is arranged circumferentially and screw
Mounting hole is corresponding；The screw end is equipped with the handle hole being recessed inwardly, and the locking plate bending is inserted into handle hole.
The section of the handle hole is at hexagon.
The beneficial effects of the utility model are: being not only simple in structure using above scheme, and there is preferable locking effect
Fruit, it is ensured that screw will not loosen in valve use, greatly improve valve working stability.
Detailed description of the invention
Fig. 1 is the front view of the locking locating snap ring of the utility model embodiment.
Fig. 2 is the side view of the locking locating snap ring of the utility model embodiment.
Fig. 3 is the side view of the locking locating snap ring use state of the utility model embodiment.
Fig. 4 is the structural schematic diagram of the utility model embodiment butterfly valve.
Fig. 5 is the enlarged diagram in Fig. 4 at A.
Specific embodiment
The utility model embodiment is described further with reference to the accompanying drawing:
As shown, a kind of butterfly valve, including locking locating snap ring 1, valve body 2, valve seat 3, stop collar 4, several screws 5；It is described
Stop collar 4 is fixed in valve body 2, and the valve seat 3 is arranged between valve body 2 and stop collar 4, and the screw 5 is circumferential along stop collar 4
It is evenly arranged, and passes through stop collar 4 and offset with valve seat 3.
The locking locating snap ring 1 is equipped with screw mounting hole 11 corresponding with screw 5, locking 1 outer ring of locating snap ring
Elastic portion 12 equipped with annular bending；The screw 5 passes through screw mounting hole 11 and locking locating snap ring 1 is fixed on stop collar 4, and
The elastic portion 12 is fitted closely with stop collar 4.
Due to the elastic force of elastic portion 12, when tightening screw 5, elastic portion 12 can generate a screen resilience to screw 5, increase
Add the frictional force being threadedly engaged, to realize the anti-loosing effect of the first weight.
1 inner ring of locking locating snap ring is equipped with several locking plates 13 that can bend fixation, and the locking plate 13 is arranged circumferentially
It is corresponding with screw mounting hole 11.
The screw 5 uses soket head cap screw, and end is equipped with the handle hole 51 for being recessed inwardly hexagonal, the locking plate
The end of locking plate 13 can be inserted into handle hole 51 by the bending to locking plate 13 in the string configuration towards the center of circle by 13
It is interior, and screw is fixed to clamp, to realize the anti-loosing effect of the second weight.
Using the handle hole 51 of hexagon and the locking plate 13 of string configuration, locking plate 13 is not only convenient for bending operation, and
It can preferably cooperate with handle hole 51, reach best anti-loosing effect.
The disc spring effect and locking plate 13 that the locking locating snap ring 1 is generated by elastic portion 12 are fixed, and are realized to screw 5
Dual anti-loose effect substantially increases the reliability of anti-loosing effect, it is ensured that screw in use, will not be due to valve vibration
It loosens, greatly improves valve working stability, and structure is simple, produce easy to assembly.
Embodiment is not construed as the limitation to utility model, but any spiritual improvements introduced based on the utility model,
It should all be within the protection scope of the utility model.
